Smith Optics Airflow Goggles keep the air flowing and the view clear. The Smith Airflow Series of ski goggles features a dual-pane lens. The lenses of the Smith AirFlow Ski Goggles have vents in the brow of the goggle lens that increase the circulation of fresh air, to keep the inner lens dry and fog-free. A semi-porous foam filter behind the Smith Air Flow Goggle vents prevents snow and moisture from infiltrating the goggle chamber. Smith Optics protects your eyes and gives you a clear view with a lineup of snowboard goggles that are ready to meet any condition on the ski slopes.
